Simplifying 12y2 + -4y + 6 = 0 Reorder the terms: 6 + -4y + 12y2 = 0 Solving 6 + -4y + 12y2 = 0 Solving for variable 'y'. Factor out the Greatest Common Factor (GCF), '2'. 2(3 + -2y + 6y2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(3 + -2y + 6y2)' equal to zero and attempt to solve: Simplifying 3 + -2y + 6y2 = 0 Solving 3 + -2y + 6y2 = 0 Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. 0.5 + -0.3333333333y + y2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + -0.3333333333y + -0.5 + y2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + -0.3333333333y + y2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + -0.3333333333y + y2 = 0 + -0.5 -0.3333333333y + y2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 -0.3333333333y + y2 = -0.5 The y term is -0.3333333333y. Take half its coefficient (-0.1666666667). Square it (0.02777777779) and add it to both sides. Add '0.02777777779' to each side of the equation. -0.3333333333y + 0.02777777779 + y2 = -0.5 + 0.02777777779 Reorder the terms: 0.02777777779 + -0.3333333333y + y2 = -0.5 + 0.02777777779 Combine like terms: -0.5 + 0.02777777779 = -0.47222222221 0.02777777779 + -0.3333333333y + y2 = -0.47222222221 Factor a perfect square on the left side: (y + -0.1666666667)(y + -0.1666666667) = -0.47222222221 Can't calculate square root of the right side.
